Genuine Walter 48Q222 Needle Bearing for Surface Finishing Tools

The Walter 48Q222 Needle Bearing is a critical OEM replacement component designed specifically for the gear mechanisms of Walter Surface Technologies' high-performance finishing tools. Engineered to exacting tolerances, this needle bearing supports rotational loads within the tool's transmission, ensuring smooth power transfer from the motor to the spindle. Using genuine Walter parts is essential for maintaining the structural integrity and operational efficiency of equipment like the Big Buff III and Line-Mate III.

Needle bearings are characterized by their high load-carrying capacity relative to their compact cross-section. The 48Q222 utilizes precision-ground rollers to minimize friction and heat buildup during extended operation. Failure to replace a worn bearing can lead to increased vibration, excessive noise, and potential damage to mating shafts or housing bores. This component is manufactured from hardened bearing steel to withstand the rigorous demands of industrial metal finishing environments.
